Environmental protection united programming method for power supply based on extended sorting method

Abstract

An united method for planning environmental protection of power supply based on expansion-sequencing manner includes making preliminary optimization on environmental protection scheme of power plant to be selected, sequencing said scheme as per total cost then loading each power plant to be selected, retiring old machine sets near the end of their service life time to form preliminary plan, sequencing environmental protection procedure selected from each power plant to be selected according to treatment cost of unit pollution, loading said procedure according to exhaust index of polluted matter in local area to finalize said plan.

Description

technical field [0001] The invention relates to a power supply environmental protection joint planning method based on an extended sorting method, which is used for globally optimizing the configuration of environmental protection measures in previous power supply planning schemes in power system planning, and belongs to the technical field of electrical engineering. Background technique [0002] The optimization scheme of power supply planning generally refers to the scheme that meets the needs of system load growth and the minimum national economic expenditure under various constraints and technical indicators. Since all the schemes equally meet the demand of load growth, it can be considered that each scheme has the same national economic benefits. Under the same benefits, the program with the smallest total cost is of course the most economical program. [0003] In recent years, with the enhancement of people's awareness of environmental protection, power environmental ...

Problems solved by technology

As for the decommissioning of existing units that are approaching or exceeding their service life, they are usually taken as known conditions during power planning, thus ignoring their optimal decommissioning strategy

[0004] In addition, because power supply planning requires quantitative analysis of factors such as power supply investment and operating costs, system power supply reliability indicators under the power supply commissioning scheme, benefits and costs of interconnection with adjacent power systems, and economic losses caused by delaying certain key power supply projects, At the same time, the influence of random factors such as random outage of units, hydrological year data changes, load growth, and economic growth must also be taken into accou...
